Summary

I successfully interviewed for an SDE Intern position at Amazon, which included an online assessment and a technical interview, and ultimately received an offer.

Full Experience

I interviewed for the Software Development Engineer Internship role at Amazon. My process began with an Online Assessment conducted on HackerRank, which consisted of two coding questions to be solved within 90 minutes. One was a modified version of wildcard characters, categorized as hard, and the other involved determining the time required for all processes to get executed, marked as medium. Following the online assessment, I proceeded to a Technical Interview. There were two interviewers, and after initial introductions, they asked me to solve two specific LeetCode problems: Gas Station and Maximize Distance to Closest Person. Both of these coding questions were of medium difficulty. Overall, I found that all the questions across my rounds were of medium to hard difficulty level.

Interview Questions (2)

Q1
Gas Station
Data Structures & AlgorithmsMedium

I was asked to solve the Gas Station problem. The challenge involves determining if it's possible to complete a circular tour, starting from any gas station, given the amount of gas available at each station and the cost to travel to the next station.

Q2
Maximize Distance to Closest Person
Data Structures & AlgorithmsMedium

I was presented with the Maximize Distance to Closest Person problem. The goal is to find the maximum distance from an empty seat to the closest person, given an array representing seats where '1' denotes a person and '0' denotes an empty seat.

Preparation Tips

For my preparation, I focused on developing good speed for online assessments, understanding that time management is crucial. I regularly practiced questions on LeetCode to improve my problem-solving abilities. Additionally, I found it beneficial to read other candidates' interview experiences to gain insight into the typical interview process. During the actual interview, I made an effort to remain calm and confident, always maintaining a positive demeanor. I tried to approach the interview as a discussion rather than a high-stress evaluation. Lastly, I always prepared unique and engaging questions to ask the interviewers at the end of each round.
